Kill Strain is a unique competitive twin-stick action shooter that pits three teams against each other in an intense battle for domination. Players are divided into two teams of five humans and two mutants, and must contend with the mysterious energy source known as 'The Strain'. When contact is made with The Strain, mutants become more powerful by spreading it further on the field and turning humans into mutants. It's up to each team to control and contain The Strain while trying to outplay their opponents.
